What defines a cluster of conditions referred to as "metabolic syndrome"?

Metabolic syndrome is characterized by a cluster of conditions that increase the risk of heart disease, stroke, and diabetes. The defining features of metabolic syndrome usually include obesity, particularly abdominal obesity, high blood pressure, and elevated blood sugar levels, which contribute to a higher risk of developing cardiovascular diseases and other health issues.

The correct answer focuses on these three critical components: obesity, high blood pressure, and an increased risk of diabetes, which illustrates the intertwined nature of these conditions. The presence of these factors is what classifies an individual as having metabolic syndrome. Understanding these relationships helps in identifying at-risk populations and implementing preventive measures. The other options do not include relevant components that define metabolic syndrome and thus do not accurately reflect the syndrome's characteristics.
